massage instrument is shown h v wav nl' example which is connected to atiexihle shaft and which serves to massage the throat. The massagedevice comprises a handle 55 in which a spindle Elfi is diournaled. (lneend of said spindle 36 is eonneeted to the lievi ble Shaft which runswithin a covering tuhe 38 said tuhe being' fastened to the handle 35 hymeans ot' a aerea' Iii. ()n the other end of the spindle a holt 155i iseeeentrirally arranged to the axis ot' said spindle. The bolt 3) of therotating spindle ltiref'ipro- Cates a rod l1 liv means of the link lll.The rod il is slidahly mounted in a easing forming pant ot' the handle35. The rod 4l is provided at hoth ends with knobs i2 which are providedwith bores adapted to reeeive pins of a earrier 43 on which a massageiinplelnent is adjustahly mounted. To vary the speed of the massagetools means for varying the speed of the armature may he employed forinstance the brushes may be moved on the ring 8 ete..

Fig. B shows in a diagramn'iatieal maxiner a device to obtain a.reciprocating mo tion from the rotary motion of the shaft 4; whichdevice may replace the eranlt shaft 12: The device comprises aninternally toothed ring :21 fixed to the motor easin;r eocentrioally tothe shaft ll. Un shaft 4 an arm 23 is fixed having at` its free end apin 24 ori which a spur rear 25 is joui'naled. The pitch diameter o gear25 is half that of the ring 2l. On the gear 25 a plate is fastenedhearing a pin 26 the axis ot' vvhieh c'utsthe pitch-circle of the-gear2. (ln the pin'i a ijod 2li*v is joul'naled which receives arectilinear' to and fro movement hy rotating the shaft L which movementmay he used to actuate`the hand 33 or any other massage instrument. Thedeviee has the advantage that the reversal of the rod 2T even at highspeeds takes place without shocks. noise and ivear being avoided.

Having described my invention what 1 claim as new is:
